[Dan VrÃtil <dvratil src gnome org>]

commit f801f926f3bf099543d620748a30edc9aeb94001

    Add View->Open Inspector action to composer
    
    The action is hidden by default and visible only when you set
    org.gnome.evolution.mail.composer-developer-mode to true.
    
    Note: we could do something similar to EMailReader...
